What is the reason for a warning message "Wrong Login" during the upload of live data of the match and how to solve it?

The most common cause of this is that the match is set as “Not Online” in WCM.

To resolve this, please follow the steps below:

1. Log in to WCM using your credentials.

2. Click on "Control Panel".

3. Use the Calendar and find a match you're looking for. Select the match(es) and click "Set selected matches Online".
